Nikon DSLR Laser Focus Sight
thingiverse
This thing attaches this laser pointer https://www.amazon.com/gp/product/B09SZ3GFMC to the eyepiece of a Nikon DSLR. Use it to focus in the dark or with microscope objectives. When you get the laser dot really small you have focus. https://youtu.be/lraxJEyZ4rk Original idea was by Allen Walls https://www.youtube.com/@AllanWallsPhotography Turn the laser off before taking your picture or it will change your exposure. Project is parametric. The FreeCAD file has a spreadsheet and you can just enter measurements for other laser hardware. Please do not do powerful lasers as I wouldn't want you to damage any of the sensors in the camera. Low power is safe. Many lasers sold by amazon are not low power.
